Answer:

The wavelength, of a sound wave with a frequency of 20 waves per second is 15,000,000 m.

Step-by-step explanation:

In this question, we have to calculate the wavelength of a sound wave of frequency 20 waves per second.

We know that  the speed of light in air/ vacuum is 3\times 10^{8}.

Now by the formula v = nλ , where v = speed of light in air/vacuum, n = frequency of the wave and λ = wavelength in meters,

we put the values

3\times 10^{8} = 20 × λ

λ = \frac{3\times 10^{8}}{20}

λ = 15,000,000 m

The population of a town is 81,712 and declines continuously at a rate of 4.1% each year. What is the approximate population of
Ganezh [65]
Data:

P (Final population) = ?
Po (Initial population) = 81712
r (rate) = 4,1% = 0,041
t (time in years) = 17

P = Po - (Po*r*t)
P = 81712 -(81712*0,014*17)
P = 81712 - 56953.264
P =24758.736
\boxed{P \approx 24759}

Answer:
B) 24759
